• Summary: “一曝十寒” (yī pù shí hán) is a classic Chinese idiom (chengyu) that vividly describes the act of working sporadically and lacking perseverance. Literally translating to “one day of sun, ten days of cold,” it paints a picture of effort that is too inconsistent to produce any meaningful results. Originating from a story by the philosopher Mencius, this term is widely used today to criticize or lament a lack of steady commitment in any endeavor, from studying a language to working on a project or maintaining a fitness routine. It's a powerful reminder of the cultural importance placed on diligence and consistency in achieving goals.

• Pinyin (with tone marks): yī pù shí hán
• Part of Speech: Chengyu (成语) / Idiom
• HSK Level: N/A
• Concise Definition: To work intermittently; to lack perseverance and consistency.
• In a Nutshell: Imagine you are trying to grow a plant. You give it a full day of warm sunshine, but then you leave it in the freezing cold for the next ten days. Any benefit from that one day of warmth is completely lost. This is the core feeling of “一曝十寒”. It describes any situation where short bursts of hard work are followed by long periods of neglect, making progress impossible. It's about the futility of inconsistent effort.

• 一 (yī): The number “one”.
• 曝 (pù): To expose to the sun, to sun-dry. Think of “exposing” something to warmth or effort.
• 十 (shí): The number “ten”.
• 寒 (hán): Cold, chilly, frigid. Represents neglect, inactivity, or a lack of effort.
• The characters combine to create a powerful metaphor: one day of “heat” (work, study, practice) is immediately followed and cancelled out by ten days of “cold” (inactivity, neglect). The ratio of 1:10 emphasizes how overwhelmingly negative the lack of follow-through is.

The origin of “一曝十寒” comes from a passage in Mencius (孟子), a foundational text of Confucianism. In the story, Mencius is explaining why some students learn well while others don't, even with the same teacher. He uses an analogy about learning the game of Go (围棋, wéiqí). He says: “Though it may be the easiest thing in the world to grow, if you give it one day of warmth and ten days of cold, it will not be able to grow.” (虽有天下易生之物也，一日暴之，十日寒之，未有能生者也。) He implies that even the most receptive student (the “easy-to-grow thing”) cannot succeed if their effort is inconsistent. This idiom is deeply rooted in the Chinese cultural values of perseverance (坚持, jiānchí) and diligence (勤奋, qínfèn). The belief is that success, especially in scholarship and skill-building, is not the result of fleeting genius but of steady, unrelenting, and often monotonous effort over a long period. A rough Western comparison might be the phrase “a flash in the pan,” but they are not the same. “A flash in the pan” usually describes a person or thing that has a single, brief moment of success or brilliance that is never repeated. “一曝十寒” describes the *process* of inconsistent effort that *prevents* success from ever happening in the first place. It is a critique of a poor work ethic, not a comment on a one-time success.

“一曝十寒” is a common and well-understood idiom used to describe a lack of follow-through in any long-term activity. Its connotation is almost always negative or self-deprecating.

• In Education: A teacher might use this to scold a student who crams for one day before an exam but doesn't study regularly. “你这样一曝十寒地学习，成绩怎么可能提高呢？” (If you study so inconsistently, how can your grades possibly improve?)
• In Personal Development: People often use it to describe their own failed attempts at forming good habits, like going to the gym, dieting, or learning a new skill. It's a common phrase in New Year's resolutions discussions.
• In the Workplace: A manager might criticize a team or employee whose work on a long-term project is done in short, unproductive bursts followed by long periods of inactivity.

It's formal enough for written essays but common enough to be used in everyday conversation among educated speakers.

  • Analysis: A very formal usage, suitable for government reports or official speeches. It shows the idiom's range from casual self-critique to serious policy statements.

• Not Just “Lazy”: A common mistake is to equate “一曝十寒” with simply being lazy. It's more specific. A person exhibiting “一曝十寒” might actually work very hard during their “one day of sun.” The problem isn't a total lack of effort, but a complete lack of consistency. They start strong but have no follow-through.
• Not “Procrastination”: This is different from procrastination (拖延, tuōyán). A procrastinator delays starting a task. A person who is “一曝十寒” starts the task, often multiple times, but fails to maintain the effort.
• Incorrect Usage: Do not use it to describe a single instance of giving up. It must describe a pattern of behavior.
  • Incorrect: 他昨天努力工作，今天就放弃了，真是一曝十寒。 (He worked hard yesterday and gave up today, that's so yī pù shí hán.)
  • Why it's wrong: This only describes one cycle. The idiom implies this has happened before and will happen again.
  • Correct: 他工作总是一曝十寒，干几天就想休息几周。 (His work is always inconsistent; he works for a few days and then wants to rest for a few weeks.)
